Such a speed, it seems that AX-12W is better for wheel mode than join mode, compared to AX-12A. But AX-12A is better for join mode, because AX-12W speed for join mode is slower. Correct me if I'm wrong.(just thinking how robotis could manage to differentiate the speed between wheel mode and join mode in one package?)

As for the CM530, I'm wondering about how fast it's clock frequency?any info about that?anyone have info about whether it will be available for international market?when?

Compared with the AX-18A and the 12A, what so special about the new motor? Is the encoder an optical one? According to the support site, the torque of the new AX-12W is 0.2Nm (2kgfcm). It seems to be way too small compared with the others. Is there a typo?
